When organisms began using photosynthesis to make food, Earth underwent significant changes, particularly in its atmosphere and ecosystems. This process, primarily carried out by cyanobacteria and later by plants, led to the production of oxygen as a byproduct, dramatically increasing the levels of oxygen in the atmosphere. This rise in oxygen enabled the evolution of aerobic organisms and contributed to the formation of the ozone layer, which protects life from harmful ultraviolet radiation. Additionally, photosynthesis facilitated the development of diverse ecosystems, as it provided an energy source for a wide range of organisms.
What else can I help you with?
How will the change in sea levels affect organism on Earth?
The change in sea levels will prevent many organisms from migrating. Marine organisms will be the most likely to adapt.
When did the biosphere begin to evolve?
The biosphere is defined as the living organisms on earth. As such, it began to evolve when the first organisms appeared. Currently, this is believed to have happened about 3.5 billion years ago.
How did the earth change when organism began using photosynthesis to make food?
When organisms began using photosynthesis to make food, the Earth's atmosphere underwent a significant transformation. This process released oxygen as a byproduct, gradually increasing atmospheric oxygen levels, which enabled the evolution of aerobic organisms and diverse life forms. Additionally, photosynthesis played a crucial role in sequestering carbon dioxide, helping to regulate the planet's climate and paving the way for the development of complex ecosystems. Overall, it marked a pivotal shift in Earth's biogeochemical cycles and the dynamics of life.
What element upon which most modern organisms depend was missing from earth's early atmosphere?
Oxygen was the element missing from Earth's early atmosphere, which eventually accumulated due to early photosynthetic organisms. This change in the atmosphere allowed for the evolution of organisms that rely on oxygen for respiration.
What is the part of the earth all organisms are found in?
All organisms are found in the biosphere, which is the part of the Earth where life exists. The biosphere includes the atmosphere, lithosphere, and hydrosphere where living organisms can thrive.

What is the term for the biological process by which the kinds of organisms on earth change over time?
Evolution

What is the scientific explanation for how life began on Earth"?
The scientific explanation for how life began on Earth is through a process called abiogenesis, where simple organic molecules combined and evolved into more complex structures over time, eventually leading to the first living organisms.
What events occurred that allowed single - celled organisms to into more complex organisms at the end of the precambrian time?
the ozone layer began to develop shielding earth from ultraviolet rays, this was hypothesized that these changes allowed species of single celled organisms to evolve into more complexed organisms
Where did homosexuality begin?
Homosexuality began wherever life on Earth began.Homosexuality began with the dawn of animal life on Earth.

Did topsoil always been present upon planet Earth?
No, topsoil takes thousands of years to accumulate. When Earth was very young, it was mostly rocks and lava. After the atmosphere settled in, and erosion of rock began, and organisms showed up, topsoil began to accumulate over the rock.
What is change of organisms over an extended period of time?
Change of organisms over an extended period of time is known as evolution. Evolution is the process by which populations of organisms change over generations through genetic variation, natural selection, and other mechanisms, leading to the emergence of new species and the diversity of life on Earth.
